# ABOUT THIS PROGRAM
#
# NAME
#	enableJournaling.sh -- Enable journaling on an HFS+ volume.
#
# SYNOPSIS
#	sudo enableJournaling.sh
#	sudo enableJournaling.sh <mountPoint> <computerName> <currentUsername>
#
# 	If the $mountPoint parameter is passed from The Casper Suite, this is the volume on which
#	journaliing will be enabled.
#
#	If the mountPoint parameter is hardcoded in this script, it will override any parameter that 
#	has been passed from The Casper Suite.
#
# DESCRIPTION
#	This script enables the journaling feature on the specified HFS+ volume.  Journaling can help
#	protect a drive against corruption in the event of power loss or power failure and can also
#	expedite the repair process if a bad sector is found.  This script was designed to take
#	advantage of The Casper Suite automatically passing the <mountPoint> parameter.
#	
#	For further description of file system journaling, see:
